What config parameters should be used to generate an encoded stream with IDR picture of NAL type either IDR_W_RADL or IDR_N_LP at regular interval? If this is possible, how to generate VPS, SPS and PPS which proceed each of these IDR pictures?

    Hi Dongning,
       DecRefreshInterval parameter is used for generating IDR picture regularly. Before every IDR, VPS SPS PPS will be generated.
    1) If this parameter is set to 1 all I frame will be IDR.
    2) If it is set to 2, alternative I frame will be IDR.
